It took a week to tidy up the use of RPCX, the general process is as follows:
Server-Side development
First of all, we need to implement our own services, which is very simple, that is to define a common method:
package exampleimport ("context""fmt")
Golang Engineer Job Responsibilities: 1, responsible for product platform system research and development work; 2, participate in the development of front-end business processes, interface protocols, document output, etc. 3, participate in project
1, go of the package is not limited to a file, composed of multiple files, compiled in fact, and a file similar to each other, composed of different files can directly reference variables and functions, whether or not exported;
2, go does not

What did bootstrap.sh help us with when we built the Fabric environment? , we know that bootstrap.sh has done three things for us:
Clone Hyperledger/fabric-samples from GitHub and enter the directory, then check out the
In the process of software development, project launch is not the end point. After the line, but also to the sampling analysis of the operation of the program, and re-construct the existing functions, so that the program execution more efficient and
Consistency algorithm-Raft
Raft status
A Raft cluster consists of several server nodes, usually 5, which allows the entire system to tolerate the failure of 2 nodes, each of which is in one of the following three states:
follower(跟随者): All
Introduction to Byzantine fault-tolerant systems
The original Byzantine fault-tolerant system lacked practicality because of the need to demonstrate theoretical feasibility. In addition, the complexity of the algorithm also increases exponentially

The previous share added two functions, one is the editing function, one saves the function
There are a few places in our program that actually ignore the wrong deal.This is not a good practice, especially because of the unexpected
Watching the go language for two days, it is time to practice practiced hand.Go's routine (routines) and Chan (channels) are simply artifacts, and it's not easy to achieve multithreading (multiple routines in go).
So the code is a fool version of
Obtaining third-party packages with commands
go get -u -v github.com/speps/go-hashids
The code is as follows:

Written in the go language, only requires file configuration, with very little code to run a Web-based management platform. The front end is built with Adminlte to use the Pjax technology without refreshes for a better experience. The backend is
Gofasion is a lightweight parsing library that facilitates the parsing of interface JSON data in the development process, and its greatest feature is the support of chained calls, which means that the target key name and key value can be obtained
Friends who have used the Python language may have used forgery_py, which is a tool for falsifying data. Can forge some commonly used data. It is very useful in our development process and effect presentation. But there is no go language version, so
